They don't have to optimize specifically for the competitor's chip, as Intel
compiler still produces probably the fastest binaries for AMD machines.  Any
general optimizations (P2, P3, and even P4 optimizations (excluding SSE2 stuff
or whatever)) are just as helpful for AMD processors as they are for Intel ones.
